You can easily use one hand to access three brightness levels and three speed flashing functions. Its 360 degree rotatable design enables full angle illumination and illuminates wherever you want increased visibility. You can wear it as a headlamp with the included comfortable headband, but you can also use it as a regular flashlight and clip to your cap, pocket, wrist or hang around your pet's neck. This is a truly versatile headlamp that you can take anywhere and use during your camping, hiking, walking, fishing and any outdoor activity. Best of all, it is also USB rechargeable so you never need to worry about the battery.
